Can't boot to DVD

While we're on the subject of startup problems, I have one too! Trying to boot to CopyCatX DVD in order to make a clone of my system drive. The startup proceeds through the blank white screen portion (very slowly), but once the screen goes to blank blue, after a minute or two, all activity stops and no further progress is made. For verification, I tried booting to Disk Warrior with the same results, and have tried both disks using both the internal SuperDrive and an external Pioneer DVD. What could cause this failure? I'm hosed if my system drive dies and I can't boot externally. Help!

Hello! You can make a bootable clone without unmounting the boot drive using disk utility and Kappy's steps below. Tom
Kappy's Steps to Produce a bootable clone
Prep external FW drive:
1. Open Disk Utility from the Utilities folder.
2. Select the backup or destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
6. Select the startup or source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
8. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Verify the settings for Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only. If they are not correct then reset them.
For added precaution you can boot into safe mode before doing the clone.

How to reset password if you can't boot from DVD?

I just bought a second external disk drive and installed Leopard on it. When it asked me if I wanted to import my information from my internal drive, I said OK, not realizing that since I had a blank password on this drive (running 10.2.8), that would not work with Leopard. One of the reasons why I bought the second disk drive is that my internal superdrive failed, and I had added on an external Lacie superdrive which does not function as a boot drive, and I wanted to run the new OS on another drive so if one drive failed, the other would work as a boot drive. However I can't boot from the DVD to reset the password on my external drive to an actual password. I disconnected the external drive and am working on my internal drive with 10.2.8. (So something I planned for worked)
I suppose one solution would be to erase the new external drive and start the whole install process all over again, making sure to add a password on this drive first. But that took about five hours and I'd really rather not. Is there some way to reset the password remotely using the OS from my internal drive to look at the external drive? Or is the non-boot from an external USB superdrive a problem unique to 10.2.8 but if I set the external drive to be the boot drive, the Leopard DVD would boot the external drive?
Thanks.

Thanks. Thankfully, when I thought about it, I realized that the computer had booted from the external superdrive to install Leopard, so I figured I'd give it a shot by selecting the install disk as the startup disk and restarting, crossing my fingers and hoping. It worked, so I was able to simply reset the password using the reset password function. Perhaps the issue with the external superdrive is that if it's not already mounted with a system disk before you restart, it won't do it after it starts up in event of failure.
And if that hadn't worked, I would have booted from my internal drive, used disk utility to wipe out the external drive, put a password on the 10.2.8 account, and done the whole install process again and migrated the account now with a password to the drive.

Can't boot from DVD using C key

I desperately need to use DiskWarrior on my startup disk. I have used it on my secondary internal hard disk with no problems. A couple of years ago my Apple keyboard went up on me and I needed a replacement immediately (I worked from home), so I ran out to OfficeDepot and bought a Microsoft keyboard that had software with it to make it run with a Mac. It has done fine for me. However, when trying to boot from DiskWarrior, I hold the C key down and it doesn't boot from the DVD, it just boots from my internal startup disk. I was able to install Mac OS X 10.4 with the DVD and this keyboard, however. DiskWarrior tech support dudes tell me it is the fault of the Microsoft keyboard. I'm not so sure (since I installed 10.4 with this keyboard). I don't want to buy an Apple keyboard "just in case." But perhaps this is a known issue by somebody "out there." Any help would be appreciated (before my startup disk explodes altogether). Thanks!

I have 3 Microsoft keyboards, going back to my G4 MDD. Usually plugged into an Apple Display, but on some occassions I've had to plug it directly into front USB port (or rear, front is accessible).
The one thing that I would do, is not just "zap PRAM" from cold boot, but boot into the Open Firmware screen and RESET-NVRAM, and see if that helps. Force the device ID list to be rebuilt, and does a more complete job than zapping can.
There have been a lot of major problems with Apple USB hub type support. I too was troubleshooting an issue and got the "run around."
The only time I've seen where someone could not boot from a DVD/CD was when the hard drive in the system directory was severely corrupt - OS X looks to find any and all bootable devices even when you boot from CD or another drive. And a damaged journaling file is even harder to fix usually.
Outside of the G4 PCI model (1999, early '00) a G4 can boot from Firewire, any problem I'd guess was a defective FW port; some FW cases themselves.
I never really use DW CD. Always always clone your system; create an Emergency boot drive to work from - and used only in emergency so you know it works and isn't just a backup. And, of course, a backup of your working system.
USB cables can flake out. Even new. The USB extension cable Apple includes being one such that has been known to be the culprit. So doubt and verify any cables and devices.
One G5 owner has a LaCie drive not even connected, but the FW cable was, hanging out the back, and would cause:
slow boot sometimes; kernel panic other times; pull the cable, life is back to normal again. FW cables and devices (not sure if LaCie has the market cornered or not) that "wipe out" FW ports, cause shorts, should be avoided (maybe banned).
I've used an MS keyboard for about 4 yrs on my G4, still running 10.4.11. Ever since my Apple split ergonomic keyboard died, and I've got 4 Apple Pro keyboards sitting around (I can palm a basketball but don't like typing on small keyboards). Currently use MS 3000 and 4000 keyboards.
There are lots of reports of Leopard where the system is not responding, but the mouse able to move, but no interaction - can't launch anything or even bring up the Force Quit dialogue. The system being totally non-responsive, and people force shutdown, with high potential of leaving the directory in disrepair.
Mac OS 10.2.5 was suppose to fix and solve USB hub problem. That updated lasted less than two weeks. USB issues have been around, as have Firewire problems. Even Windows Vista can loose track of and get confused by unplugging/replugging devices multiple times that it looses the device ID.

I can not boot from DVD or USB to install

I have a 27 in iMac with i7 processor. For reasons I wont get into (lets just assume I have the right reason) I want to do a complete fresh install of Snow Leopard and start completely over.
When I use OPT to select the SL DVD to boot, all I get is the apple logo, no spinning wheel, i let it sit that way all night still didnt work. If I force boot the SL DVD using C, same thing. So I tried formatting an external USB hard drive as a GUID drive and had the install residing on there, when I use OPT when booting the USB is not an option, nor is is listed in startup disks either.
I can not do a fresh install, and i have followed loads of tutorials online, but my DVD never does boot.

You need the discs for your computer. No other discs will work.
The retail copy of 10.6.0 doesn't have the necessary drivers for your computer, nor does 10.5. Your computer should have shipped with 10.6.1.
I think the inability to boot from USB is due to an invalid operating system being installed on the drive.

Can't boot from DVD or external drive

Because of recent slow performance on my iMac G5 I ran disk utility and repaired permissions, then clicked Verify Disk. It reported minor errors in directory files and said I should repair them. I tried starting up from the MacOS X installation DVD, but I get a spinning beach ball and a symbol with a circle with a diagonal line through it (like a Do Not Enter sign). I had to unplug the computer to reboot.
Using another computer, I made a startup disk on an external hard drive and tried booting the iMac from that, but I get the same beach ball and symbol. Tried another OS X DVD with the same result.
I am able to boot from the internal hard drive only, but then I can't do a disk repair. I have already reset the PRAM, but that didn't help.
Any suggestions ??? Thanks.

Because of recent slow performance on my iMac G5 I ran disk utility and repaired permissions, then clicked Verify Disk. It reported minor errors in directory files and said I should repair them. I tried starting up from the MacOS X installation DVD, but my G5 still starts from the hard disk and I am therefore unable to repair rthe hard disk.
Can I create a new startup disk by copying my installation disk, leaving off the installation software, and then start my Mac using Option "C".
On my previous Macs I always used Norton Utilities to repair my disk and recover files - are ther any similar packages available for OS X (10.4.7)?

Cannot boot from DVD since 10.4.6 update.

My Quad cannot boot from the Superdrive at all.Upon updating I decided to repair permissions from the DVD but everytime I got to the Apple logo the fans powered up,full tilt. I had to turn the Quad off from the power button and start up holding down the mouse, in order to eject the DVD.
As far as I remember, I allowed the computer to start up twice, and disconnected all peripherals whilst updating.
I've tried zapping the pram and resetting the nvram to no avail.I've inserted Disk Warrior and that will not boot. The computer runs fine from the HD (although there was one occasion when, briefly, a small OS9-style Mac monitor appeared with a question mark, then made way for a proper boot), but I'm really concerned at this problem. I do not want to wipe the system drive and start from scratch,since I've only just finished migrating a whole buch of software from another G5, and I have TV job looming.
Incidentally, both my other G5's and Mac Mini updated with no perceptable problems. Can anyone shed any light on this and, perhaps, offer a solution (other than a wipe ! ).
Thank you.

Any installation can theoretically cause harm. If you aren't backed up, you may be forced to use Target Disk Mode if you can't boot a DVD, or an external DVD burner that supports booting. Both LaCie and Otherworld Computing have external Firewire DVD drives that support booting. Target Disk Mode is described here:
http://docs.info.apple.com/article.html?artnum=58583
Fortunately when you boot via Firewire or use Target Disk Mode, you bypass the hard drive's bootloading software, which you don't when you use the internal optical drive.

My 27" iMac Freezes, Won't boot from DVD

My iMac has started to freeze up every few minutes. Every so often, it becomes unresponsive; the mouse cursor still moves (sometimes it turns into a beach ball), but I can't click or type anything. Whenever this happens, the hard drive begins to churn as if it's reading or writing something big. This usually lasts only about thirty seconds to a minute, but it's happening with frustrating regularity.
I've been trying to troubleshoot this for a few days, now. I'll walk you through the steps I've tried so far.
I ran a check on the hard drive with Disk Utility. This came back with a message about the files/directories not matching up with their expected counts. The solution it suggested was to boot from a Snow Leopard disc and let Disk Utility run a Repair Disk while the startup drive is not mounted. It was at this point that I realized that I couldn't boot from the dvd. Whether holding 'C' or 'Option', when it tries to boot from the disc, it gets to the Apple logo and then hangs.
I kept researching and found a workaround; boot into Single User Mode and perform fsck, which fixed the Disk Utility error, but did not solve the freezes/noises, and I still can't boot from the dvd.
Any ideas?

Thank you for your prompt response.
Well, I'm not sure if I explained it clearly. Holding the Option key does indeed bring up a list of bootable devices. The problem arises when control is passed to the Snow Leopard disc. The Apple logo flashes, I can hear the optical drive being accessed, but then it locks up.
I should also clarify that it's not the disc that came with the iMac. I just moved and can't find the original disc, so I borrowed my neighbor's (which came from a Macbook he bought after mine (which I bought last year)). I am under the impression that Macs can't boot from discs that are older than the version of OS X that they shipped with. I wouldn't think that's the issue, here, as his came out later than mine, but I've still got a lot to learn about life in the Appleverse.
My data should be safe--I've got an up to date Time Machine backup on an external drive. The performance issues aside, I'm really looking to understand the underlying problem(s) here.
So, one option is that the RAM might be bad. I can test that by swapping out each DIMM and checking if the problem is resolved. One thing I don't understand, though, is why bad RAM would manifest as the hard drive being accessed. Is there a definitive way to test the logic board, as there is for testing RAM?
Also, I keep thinking of other little syptoms which may or may not be related.
Recap of Symptoms:
Magic Mouse occasionally loses its magic (right click, multitouch, etc.) and needs to be turned off and on.
Free disk space fluctuates by as much as eight gigs (without my intervention).
System stalls (accompanied by HD access sounds) multiple times per hour.
Can't boot from dvds (though, this could be a version problem).
**Fixed: Disk Utility Verify Disk error.
I do understand that this might be a hardware error, and I certainly know how much trouble that sort of thing is to find/fix. I'm definitely willing to open the case and swap out DIMMs and drives, but not until I've exhausted my software solution options. *crosses fingers*

Kernel panic when booting from DVD or external drive

Hey Folks,
I have a 13" MBP, seems to run fine for the most part.
However, I can't boot from DVDs or external hard drives. Disk Warrior, my and a tech support buddy of mine's OSX Snow Leopard DVDs, and external boot disks all cause a kernel panic when selected from the alternate boot menu when rebooting with alt.
The DVD/External spins up, the loading spinner goes for about 20-30 seconds, and then BAM - Kernel panic. I'd reinstall OSX... but I can't!
Any suggestions? I'd rather not send the computer to a tech for a week - I need it daily for work.

How can I boot from my recovery dvd to reach the system recovery C: on a extern hard disc

I think a have a virus in my notebook Pavilion 15 and want to restore my C partition with a system back up. I made this system back up a month ago and it is stored on a extern hard disc. I have also made a recovery dvd. How can I boot my notebook from my dvd to start the procedure? I have 2 partions on my notebook. The second partition contains My Documents.
Thanks in advance.
Tineke

It is unlikely that the back-up of the system recovery, that you have stored on an external drive, will be useful in recovering your computer. Please see HP PCs - Performing an HP System Recovery (Windows 8), for instructions on using the HP Recovery Disc set your created earlier. Typically, the disc set is 4 to 6 DVDs.
If you have any further questions, please don't hesitate to ask.

Can I boot and install Tiger on a G4 running 9.2.2 from an external DVD

I have a Power Mac G4 (PCI Graphics) computer running OS 9.2.2. Firmware version I believe is 3.2.8. I purchased OS X Tiger DVD. I do not have a DVD drive on this Mac. I cannot seem to start up the Power Mac in Target mode via firewire. When I checked Apple website this Mac is not on list as able to be a target volume. Therefore, to avoid ordering CD's from Apple, I was hoping to buy an external DVD drive and use that to install from. Before I buy the new drive, I wanted to be sure this will work. Any help or suggestions are greatly appreciated.

Welcome to Apple Discussions!
The PowerMac G4 PCI Graphics can't boot from Firewire.
It also can't run Target Disk Mode.
The AGP Graphics was the first one that could.
That's documented in the articles here:
http://docs.info.apple.com/article.html?artnum=58606
http://docs.info.apple.com/article.html?artnum=58583
Make doubly sure it is a PCI graphics by reading this article:
http://docs.info.apple.com/article.html?artnum=58418
The PCI graphics needs no firmware update.
But I would make sure you have at least a 20 GB hard drive and 512 MB of RAM before installing and following the specs for your machine when it comes to the RAM

     Q. What sizes of USB Flash sticks are supported?
     A. USB Flash sticks are supported in 64, 128, and 256 MB sizes. No other sizes are supported.
     Q. Can I use any USB memory stick for this application?
     A. No. Only Cisco USB memory sticks are supported.
Q. Can I boot an image directly from the USB Flash module?
A. Yes. USB drivers have been added to rommon, starting with version 12.4(13r)
     Q. Can I format the USB Flash module on the router?
A. Yes. You can format the module on either a router or a PC. You must specify "FAT16 file system" as the file system for the PC format process to use.
If your setup satisfies above conditions you can get the router to boot up with the IOS on the USB flash
If you are in ROMMON mode, use 'dev' to find out the name of the USB Flash (should be usbflash0).
set BOOT=usbflash0:
If you are in the router,
boot system flash usbflash0:

Can't boot from hard disk or from windows 7 recovery dvd

I have a 970A-G46 motherboard.
I can't boot from hard disk or from a windows 7 recovery dvd.
If I move the hard drive to another PC, it boots fine.
If I put the DVD in another PC's dvd drive, it can be accessed.
This machine will boot from an Ubuntu dvd and I can then access the HD directories and the recovery dvd.
What do I need to do?
Help and thanks

"I can't boot from hard disk or from a windows 7 recovery dvd."
What is that DVD from? Is it from a previous computer of some kind? Same question for HDD and the OS on it.

10.6.6 update - can't boot, installation OS from DVD fails

hi all,
I have updated to 10.6.6 yesterday and since then I can't boot my MBPro. It freezes at the initial grey screen with Apple logo and "loading" wheel spinning (initially an installation progress bar appears, but vanishes after a while).
I tried reinstalling Snow Leopard from DVD, but it fails "The content of this disk can't be changed. Mac OS X couldn't be installed on this disk." I tried verifying / repairing the hard drive using the Disk Utility, but here I also get an error: "Disk utility can't repair this disk..disk, and restore you backed-up files".
I ran the Disk Utility verification of my HD about a week ago, all worked OK then.
Any ideas how I can get to my hard drive?

Was Boot Camp or File Vault ever used?
Do you have a backup?

Weird screen pattern freezes iMac, can't boot from HD or DVD

I woke up today to find the screen of my iMac black with a sparse pattern of bright pixels on it. I wasn't able to power down holding the Power buton so I unplugged it and left it for a bit before plugging back in. I was then able reboot without any problems. Then a few hours latter a weird pattern appeared across my screen, kind of rolling, animated in spots as seen here:
I powered down, started it up and the screen had this pattern on it:
It froze during startup at the point shown in the photo with the Apple logo. I powered down, unplugged, plugged back in and then tried booting up from my Snow Leopard install disc. It also froze on the logo screen. Another attempt brought up the "You need to restart your computer…" message in different languages shown here:
I figured it was having a kernel panic so I did some searching around and followed instructions on The X Lab - Resolving Kernel Panics page and Apple's Kernel Panic Troubleshooting page. I unplugged everything but my mouse (wireless keyboard) and tried booting into Safe Mode. The screen still had the same pattern but it froze again during startup, the grey progress bar having disappeared.
I can't boot from my hard drive or from a DVD and the pattern is always on screen when I turn the iMac back on. I can't run Apple Hardware Test. I'm stuck but I'm wondering if anyone knows what the cause might be or has any suggestions on how to fix it or even get it to boot up somehow.
I have TechTool Pro and a large flash drive. I'm going to try creating a bootable USB drive with Snow Leopard on it from this backup computer and try to get TechTool Pro on it as well. I'll report back but I'd really appreciate any feedback on this problem.

Some things to report. First, the night before any of this happened, I noticed the fan was running when there wasn't really any reason for it. The computer was idle, no major tasks running. I'm wondering if perhaps the videocard overheated and is causing problems. Perhaps the temperature sensors are screwed up?
Today I got a USB keyboard hooked up and reset the PRAM. Still unable to boot but the pattern on the screen did change from the mess of b&w squigglies above to vertical bars as shown here:
Trying to boot normally or in Safe Mode both result in the spinning wheel freezing and halting startup.
I found powering down then gets weird. It's like it tries to turn on again but can't after a second. Or sometimes it will and the mouse lights up, I can hear the optical drive but the screen stays dark. At that point I need to unplug and try again.
I tried booting from Snow Leopard install DVD during one of these weird cycles and could hear it trying to access the optical drive but I don't believe it even got to the chime stage.
I attempted booting from the install DVD again after unplugging. No luck there but instead of a frozen spinning wheel, it brings up the "You need to restart message…". Other methods don't do this.
Still at a loss to find a reason for this but it appears to be a hardware problem, no doubt the video card based on the screen issues. Does any of this shed any light on what the problem is or (even better) how to fix it?
